BACKGROUND

The City of Greenfield is located in the Central Coast region of California in the heart of

Salinas Valley near the Salinas River. It is in northeastern Monterey County, along

United States (US) Route 101, approximately 95 miles south of San Jose. The City has

a total area of 2.1 square miles and is surrounded by unincorporated agricultural land.

Approximately 91% of the City’s residents identify as Hispanic or Latino, with a

population of 18,937 recorded in the 2020 U.S. Census. The City is classified as a

disadvantaged community (DAC), meaning that residents predominantly earn below

80% of the State median household income. The City’s existing wastewater treatment

plant (WWTP) consists of a primary treatment plant followed by a secondary pond

system, with effluent disposal by percolation ponds. The plant has under-performed in

recent years, and not capable of complying new waste discharge requirements issued

by the Regional Water Quality Control Board (Regional Board).

On September 25, 2020, the RWQCB adopted WDR Order No. R3-2020-0020 for

Discharges from Domestic Wastewater Systems with Flows Greater than 100,000

Gallons per Day (General Order). This General Order includes more stringent effluent

quality limitations to achieve groundwater quality objectives, including an effluent total

nitrogen limit of 10 mg/L. The City will be constructing a new 2.0 mgd modular package

membrane bioreactor (MBR) treatment plant, capable of meeting these more stringent

treatment requirements. The new WWTP will be located on the same site as the

existing primary plant facilities, on the northeast end of Walnut Avenue.

As part of the new WWTP construction, the City has a procurement agreement for the

packaged membrane bioreactor (MBR) treatment modules, that will be manufactured

and installed by Cloacina, Inc., Arroyo Grande, CA. The contract with Cloacina, Inc. will

be assigned to the awarded construction contractor.

This project will receive grant funds through the Clean Water State Revolving Fund

(CWSRF), and the funding Agreement was issued April 8, 2026. Once an agreement is

finalized with CWSRF the District intends to issue bid documents for construction, with

construction award anticipated Fall 2026 at the earliest. The City desires to have the

CM team on board by summer 2026, to begin early tasks that may include value

engineering, final plan check reviews prior to bid, and assisting the City with various

tasks including permitting, environmental compliance and other activities related to

construction startup. The Project construction duration (which includes bid period,

construction, close-out/substantial completion, issuance of record drawings/O&M

Manuals) is anticipated to be 36 months.

INFORMATION AVAILABLE

Consultants are encouraged to review current available project-related information

electronically; such documents will be made available by download via PlanetBids. A

site visit to the existing WWTP site may be conducted only during the day of the pre-

proposal meeting. This site visit will be conducted with all consultants as a group; no

individual site visits will be accommodated. Consultants shall be prepared to caravan in

their own vehicles to the WWTP site location, guided by City staff and the City Engineer.

Consultants must contact Alejandra Gil-Mares, Assistant Engineer, at agil-
